Patented Nov. 8, 1921 Application filed January 14, 1921. Serial No.437,295.

To all whom may concern:

Be it known that I, ABNER JUDSON LURRY,

a citizen ofthe .United States, residing at Baton Rouge, in the parishof East Baton Rouge and State of Louisiana, have inventing, lacing, ordarning of fabric known as ress cloth, which is a kind of material usedor the wrapping of oleaginous products while undergoing compression inhydraulic presses, to theaction of which such products are subjected forthe the oil therefrom.

This press cloth becomes torn and rent. in

places which renders it unfit forefi'ective use, and which makes itdifficult to handle involving waste of time and labor.

It is an object ofthe invention, therefore, to provide an improvedmachine in which this press cloth may be repaired at the m ll quicklyand at a minimum of ex ense, while providin for the convenience o theopera- Q tor and For his personal comfort re airing operation.

b e inventionmoreover' aims to provide a machine for carrying out theabove ob jects, which will be simple in construction and inexpensive tomanufacture, and which will be adjustable with respect to a seatprovided for the operator.

With the foregoing and other objects in view, the invention will be morefully described hereinafter, and will be more particularly pointed outin the claims appended hereto. 0

Fig.8 is a view in elevation of one of the movable jaw holders; and

Fig. 9 is an elevational view of one of the fixed 'aws. Re 81'11I1 moreparticularly to the drawings, accor ing to the invention I provide asupport which preferably a carpenters saw bench made up of supportinglegs 1 and a pair of beams 2 and fixed to the legs and extending in asubstantially horizontal direction with a slot 4 left between them. Aseat '5 for the operator is either fixedly or adj ustably secured uponthe support, which is constructed preferably near one end thereof so asto leave ample space on the support for the clamping device, which is ofa duplex character.

The clamping device consists of a pair of heads 5 and 6 made, as shownin F igs. 3 and 4, of a substantially diamond shape in 916- vation andprovided with legs 7 adapted to receive bolts 8 which extend through theslot 4 of the support and are adjustable therein. Clamping nuts 9 ontheends of the bolts are adapted to secure the device in the adjustedposition on the support In this way the clamping device may be movedtoward or from the seat 5 to accommodate the operator. A trough beam 10having ,diveigent side walls is mounted upon the central and uppermostportions of tlie'heads 5 and 6 and extends between them lyingsubstantially parallel with the beams 2 and of the support. This troughbeam may be secured to r the heads 5 and 6 in any suitable manner, bolts11 being indicated as this method of fastening renders it possible todisassemble movable jaws which clamp it securely in place andprevent thecloth at the opposite sides of the rent from falling away. The fixedjaws are indicated at 13 and let, and they are supported in convergentrelation at opposite, sides of the saddle. One of the jaws 13 is shownmore particularly in" Figs.

- 5 and 9, where these jaws are illustrated'to be provided withsupporting arms 15 and 16 formed with angularly disposed bearing bosses17 and 18 for cooperating with similar complemental bearing bosses 19and 20 carried by the opposite heads .5 and 6.

The bearings thus-provided are adapted to receive rock shafts-21 and 22which carry collars 23 secured thereon by set'screws 2d 30, one such jawbeingshown in Figs. 6 and 7. The upper face of each jaw is provided withcorrugations31 and with bolt holes 32 near its longitudinal centralportion. Re-

' cesses 33 are cut in the sides ofthe movable jaw also preferably nearthe longitudinal center thereof, the under sides of the jaw being cutaway as indicated at 34. The movable jaw 3O is adaptedto be removablyreceived in .a holder 35 shown more particu larly in Fig. 8 providedwith upstanding lugs 36 slidingly receivable in the recesses 33 in thejaw and having bolt holes 37 in which to receive the fastenings whichpass through the bolt holes 32 of the jaw.

A slot 38 is made in the web 39 of the holder to receive the shaft 22andto permit the holder to slide at right angles'to theaxis of the shaftwhil'e' permitting theshaft to rotate freely in .the holder. An.eccentric strap 40 projects outwardly from the holder and formstherewith a recess in which the eccentric is housed. As .moreparticularly shown in Fig. 4, the eccentrics 4E1 and 42 operate withinthe housing thus formed and act to shift the movable jaws 29 and 30toward and awayfrom the fixed jaws let and 13 respectively. 1

A set collar 43 on each of theshafts is fitted up against. the eccentricand holds the same in the housing provided by the holder.

A- second set-collar 44 on the opposite side of each shaft provides anabutment against 'which. onezend of aflcoilspring a5 seats, the"otheri-e nrl' pressing against a washer 4'6 and washerjagainstthe'holder so as .to resist "tami 'orthe shaftsiwhich' results in the"shafts being thus yieldingly" held in adjusted position. These parts44-, i5 and 4:6 are also for the purpose of causing the two ends of themovable jaw to be equally spaced from the stationary jaw, when open, andon the other-hand to permit the movable jaw to adjust itself against anyunevenness of the material when under pressure.

Plates a7 and 48 are secured to the lower sides of the arms 1:) and 16of the stationary jaws and are spaced from the jaws at their upper endsin order to provide slots all) shown in Figs. 4.- and 9 in which topermit passage of the cloth.

In the use of the device, the operator seats himself upon the seat 5with one leg to each side of the beams 2 and 3. He then draws theclamping device toward him until it is at a convenient position at whichtime the nuts 9 may be tightened to secure it in place. Opposite ends ofthe cloth to be darned or laced are threaded through the spaces be tweenthe two sets of clamping jaws, while these jaws are open and the endsare brought together sul'istantially upon the middle high portion of thewooden saddle 12.

The cloth is then clamped within the aws which will hold it in properposition. An awl. is used to punch holes through the cloth at oppositesides of the meeting edges and a needle with thread is inserted in theoppositedirection through the holes made by the awl, preferably beforethe awl withdrawn so as to facilitate this operation.

The machine affords the operator the opportunity to firmly hold the workin. a position that will enable him to adjust himself to the work in thefashion of a shoemaker with the work strapped to his knee, or the tailorpinning it to his pants near the knee and to this end the arrangementand disposition relatively of the seat and the clamping device is suchthat the work will it as closely as possible in the lap of the operator,and it will permit the operator to move his legs closely as possibletogether and about the machine so as to prevent fatigue and, at the sametime. to allow the cloth ends to pass freely outside of the legs.

' The movable jaws 29 and 30 are opened by swinging the handles 26 and28 over toward one another until they strike the opposite shafts oradjacent parts. the handles then being crossed. After the material isplaced in the device. the levers are swung in an opposite direction,which moves the eccentric to the position shown at theleft in Fig. tthereby clamping the material between the jaws.

The device is useful, not only in securing pieces of cloth together, butalso in darning holes-in cloth and securing rents of every description.

It is obvious that various changes and modifications may be madeinthe'details of construction and design of the above'sp'ecificall ydescribed embodiment of this invention without departing from the spiritthereof, such changes and modifications being restricted only by thescope of the following claims.
